Reconstituting a lyophilized peptide

Preparing a vial for laboratory research

Lyophilized (freeze-dried) peptides are dissolved in a diluent before use in the lab, most often bacteriostatic water.

  1. Let the sealed vial reach room temperature before opening to limit condensation.
  2. Wipe the rubber stopper of the peptide vial and the diluent vial with an alcohol swab.
  3. Draw the planned volume of diluent with a sterile syringe.
  4. Insert the needle and let the diluent run slowly down the inside wall of the vial, not directly onto the powder.
  5. Swirl gently until the powder has fully dissolved. Do not shake.
  6. Label the vial with the date and the concentration.

Use the Peptide Calc to work out the concentration and the matching reading on a U-100 syringe.

Storage and handling

Keeping research material stable
  • Unopened, lyophilized: store in a freezer at −20 °C, protected from light and moisture.
  • After reconstitution: keep refrigerated at 2–8 °C.
  • Avoid repeated freezing and thawing.
  • Keep vials sealed and upright, and handle them with clean gloves.

For laboratory research use only. Not for human or animal consumption.

How to read a certificate of analysis

What each result on a COA means
  • Lot number: must match the lot printed on your vial label.
  • Purity (RP-HPLC): the share of the sample that is the target peptide.
  • Identity (MS): mass spectrometry confirms the molecule is the correct one.
  • Endotoxin: the level of bacterial endotoxin measured in the sample.
  • Testing lab and date: who tested the lot and when.

Find the report for your lot on the COA page.
